My S7 can still do it. The reason newer phones can't is because they lack an aux jack: the wire is used as an antenna. Another great reason to keep the headphone jack.

I don't know the current situation, but in the past most US carrier-sold phones have not had the antenna pin connected on the chip.

I'm not sure exactly what it is, though I know all the S7s do. I suppose it may be carrier-locked? I bought mine unlocked, not via a carrier. It's a handy feature, though. Free music and entertainment with zero data spent. I've got to wonder why people moved away from it. No signal issues either.

<conspiracytheory>That's probably why the phone manufactures were asked by Google and the carriers to remove that feature.</conspiracytheory>

I bought a Nokia 6.1 phone and was pleasantly surprised to discover FM radio on it.

Still is, on moto's at least not sure about other.

All my Android and WP phones are perfectly able to do it.
